大家可以看完教程亲自尝试下,也可以直接执行一键安装命令,整个过程大概10分钟左右,我在四台不同的机器上执行过该命令,由于网络原因,5-15分钟不等。
如本文章内容与通过一键安装下载的不同,以一键安装的为准,一键安装版本会继续更新,v1.3.0版本支持memcache 和 redis。
执行完一键安装后,直接访问 你的IP:8081 访问即可出现phpinfo页面的内容
本次部署,旨在单台服务器上使用docker构建集成环境,并运行Nginx+PHP项目
$ sudo yum update
$ sudo yum remove docker \ docker-client \ docker-client-latest \ docker-common \ docker-latest \ docker-latest-logrotate \ docker-logrotate \ docker-selinux \ docker-engine-selinux \ docker-engine
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo yum makecache fast
sudo yum -y install docker-ce
sudo systemctl start docker
[root@runoob ~]# docker run hello-world docker run 命令会先在本地查找 hello-world镜像,如果本地没有会自动下载一个到本地,然后在运行hello-world
$ sudo yum remove docker-ce $ sudo rm -rf /var/lib/docker

在/root目录下 新建 docker-env文件夹,这里面包含nginx和php的镜像构建的所有文件和配置,以及Dockerfile
cd /root mkdir docker-env //建立文件夹 cd docker-env/ mkdir nginx //存放nginx相关文件 cd nginx/ touch Dockerfile && mkdir conf && mkdir logs && mkdir html && mkdir www //创建Dockerfile文件,建立nginx的配置目录和日志等目录
[root@mdm nginx]# cat Dockerfile # 基础镜像 FROM centos # 维护者 MAINTAINER 271648298@qq.com # 安装wget下载工具 RUN yum install -y wget # 切换到usr/lcoal/src/目录,相当于cd,并可以用cd 代替, 但docker官方不建议用cd WORKDIR /usr/local/src # 添加远程文件到当前文件夹, 注意:后面有个点(.) 代表当前目录。ADD可以添加远程文件到镜像,但COPY仅可以添加本地文件到镜像中。 ADD http://nginx.org/download/nginx-1.17.0.tar.gz . # RUN,在镜像内运行解压命令 RUN tar zxvf nginx-1.17.0.tar.gz # 切换目录 WORKDIR /usr/local/src/nginx-1.17.0 # 更新yum,可不执行 # RUN yum -y update # 安装必要的软件和添加nginx用户 RUN yum install -y gcc gcc-c++ glibc make openssl-devel RUN yum install -y libxslt-devel -y gd-devel GeoIP GeoIP-devel pcre pcre-devel RUN useradd -M -s /sbin/nologin nginx # 挂载卷,测试用例(这里的挂载卷,不可以指定本机的目录,不够灵活,一般会在 启动容器时通过 -v 参数指定挂载卷,或在docker-compose.yaml文件中指定,都可以指定本地目录) VOLUME ["/data"] # 编译安装nginx RUN ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --with-file-aio --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_image_filter_module --with-http_geoip_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_degradation_module --with-http_stub_status_module && make && make install # 切换到Nginx的配置目录 WORKDIR /usr/local/nginx/conf # 建立子配置文件夹,个人爱好,可以不建,或者叫其它名称都可以,但最好不要带特殊符号, RUN mkdir vhost # 设置变量,执行命令时,就可以省略前缀目录了 ENV PATH /usr/local/nginx/sbin:$PATH # 暴露端口 EXPOSE 80 # the command of entrypoint ENTRYPOINT ["nginx"] # 执行命令,数组形式, "-g daemon off;" 使我们运行容器时,容器可以前台运行,不会退出 CMD ["-g", "daemon off;"]
[root@mdm nginx]# docker build -t centos_nginx:self . //注意,最后有个点(英文句号), centos_nginx 是镜像名称,self是打的标签,跟版本号一样的意思
docker run -d -p 8082:80 --name=test_nginx centos_nginx:self //启动一个容器,输出成功会提示一串字符串 -d 是守护进程运行的意思,即容器后台运行不会退出 -p 映射端口号,宿主机端口:容器端口 --name 容器名称, 最后的 centos_nginx:self 是使用的镜像:版本号 docker ps -a //查看所有容器列表,显示如下,说明nginx容器已经正常启动 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES d51f2c95b66c centos_nginx:self "nginx -g 'daemon of…" 5 seconds ago Up 4 seconds 0.0.0.0:8082->80/tcp test_nginx 通过 curl 127.0.0.1:8082 命令,能看到 Welcome to nginx 等英文提示,即说明一切OK 下面我们进入容器,进入容器有很多方式,还可以通过ssh进入,这里我只介绍我常用的方式 docker exec -it d51f2c95b66c /bin/bash //这种方式进入,不会造成容器的关闭, docker attach 进入再退出会造成容器关闭, 后边的 /bin/bash 也可以换成 /bin/sh(比如alpine 基础镜像) 进来后查看Nginx的配置文件 [root@d51f2c95b66c /]# cd /usr/local/nginx/ [root@d51f2c95b66c nginx]# ls client_body_temp conf fastcgi_temp html logs proxy_temp sbin scgi_temp uwsgi_temp 可以自己了解下这个版本的nginx的目录结构,方便后期配置 通过exit 命令退出容器即可
cd /root/docker-env/nginx/conf touch nginx.conf // 该文件将来要挂载到容器中,作为Nginx的配置文件, 你可以通过 docker cp d51f2c95b66c :/usr/local/nginx/conf/nginx.conf /root/docker-env/nginx/conf 复制一份Nginx容器的原生配置文件,也可以使用下面我的nginx配置文件

[root@guangai-app php]# cat Dockerfile FROM php:7.1-fpm-alpine3.9 MAINTAINER 271648298@qq.com # install redis RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories \ && apk update \ && apk add --no-cache libmcrypt-dev freetype-dev libjpeg-turbo-dev \ && docker-php-ext-install mcrypt pdo_mysql \ && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ --with-png-dir=/usr/include/ \ && docker-php-ext-install -j$(nproc) gd \ && mkdir -p /usr/src/php/ext/redis \ && curl -L https://github.com/phpredis/phpredis/archive/3.1.6.tar.gz | tar xvz -C /usr/src/php/ext/redis --strip 1 \ && echo 'redis' >> /usr/src/php-available-exts \ && docker-php-ext-install redis
文件内容看起来很少,因为使用了docker的官方的php镜像,基于alpine系统,一个不到5M的linux系统
我这里仅安装了必要的gd、mysqlpdo、redis等库,如需其他库,可以自行添加
具体php:7.1-fpm-alpine3.9中包含了什么,可以到官网查看 地址:php/Dockerfile at a7e2de0e8f2b902bc36be6f5d61c0b4fcd1052ff · docker-library/php · GitHub
下面我们构建属于自己的PHP镜像
docker build -t alpine_php:self . //注意,最后有个点(.)
docker run --name myphp-fpm -v /root/docker-env/nginx/www:/www -d alpine_php:self
sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose //这里可能会很慢 sudo chmod +x /usr/local/bin/docker-compose docker-compose --version
[root@guangai-app ~]#cd /root/docker-env [root@guangai-app docker-env]# ls docker-compose.yml nginx php 可以看到,这里有我们刚完成的nginx 目录和 php 目录,除此之外还有一个docker-compose.yml文件
[root@guangai-app docker-env]# cat docker-compose.yml nginx: build: ./nginx volumes: - /root/docker-env/nginx/html:/usr/share/nginx/html - /root/docker-env/nginx/conf/nginx.conf:/usr/local/nginx/conf/nginx.conf - /root/docker-env/nginx/conf/vhost:/usr/local/nginx/conf/vhost - /root/docker-env/nginx/logs:/usr/local/nginx/logs - /www:/www ports: - "8081:80" links: - php php: build: ./php volumes: - /www:/www
[root@guangai-app vhost]# cat test-php.conf server { listen 80; server_name localhost; location / { root /www/api_wx_klagri_com_cn/public; index index.php index.html index.htm; if (!-e $request_filename) { rewrite ^(.*)$ /index.php?s=$1 last; break; } } error_page 500 502 503 504 /50x.html; location = /50x.html { root /www/cms/public; } location ~ \.php$ { root /www/api_wx_klagri_com_cn/public; fastcgi_pass php:9000; fastcgi_index index.php; #fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; fastcgi_split_path_info ^(.+\.php)(.*)$; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; set $real_script_name $fastcgi_script_name; if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") { set $real_script_name $1; set $path_info $2; } fastcgi_param SCRIPT_FILENAME $document_root$real_script_name; fastcgi_param SCRIPT_NAME $real_script_name; fastcgi_param PATH_INFO $path_info; include vhost/my_params/api_wx.conf; } }
docker-compose up -d //-d 后台运行 修改nginx配置后,通过 docker-compose up -d --force-recreate 重启
然后通过你ip+端口号访问 ,比如http://59.110.217.236:8081/index.php
OK
